Once upon a time, chilluns, there was a wonderful island with a Woolworths and a Placemakers. Many were the islanders who shopped there, and happy they were because they were good places to shop and good places for good nattering.
Sadly, some islanders habitually used their feet to get there. Yes, I know that's terribly bad taste, and that everyone should use an SUV, or even better a Hummer on steroids with loose tappets, but there are obviously loonies who think feet are provided for walking with on footpaths.
Even more sadly, most of those despicable walkers came down the hill to the W and the P, and, being people of brain and efficiency, they didn't walk right round and come in through the same entrance as all those steroidal Hummers. No, they took a clever shortcut down the bank at the top corner of the Woollies/Placemakers place.
Sadly the bank was steep, and somehow got slippery when wet stuff fell out of the sky, so the shortcut was a tad dicey in the downward direction, and even tadder in the upward when them people was carrying a load of goodies what they'd bought.
So along came this 'Barking Mad' Bloke, who said, 'Aha, let's fix that. Let's build steps down that bank, with a handrail even, then people can't fall flat and bend-or-break important bits.'
'Whatta good idea,' chorused Other Mad People, so the BMB asked the boo-rock-rats to build the steps with a dollar or two of the dosh they'd extorted from all the islanders. 'No!' shouted the boo-rock-rats. 'Why not?' quoth the BMB, 'it would be good for people.' 'Cause,' explained the boo-rock-rats to this BMB dummy, 'on page 57 of the sacred SLIPs manual it says under "Rules" that you can't use public dosh to get access to private parts (besides, we don't understand this "good for people" stuff).'
So there you are. Akl Qaeda Council, which loves to send bureaucratic car-bombs to blow your pleasant island life to smithereens, has Rules, and the Rules say that if the start of a berm-crossing is public (tick), and the middle is public (tick), and the other end is public (tick), but one nanometre past the other end is private parts (doh!), even if them private parts is public shops, ya can't build that there public crossing with public dosh.
'So jus' keep fallin' on your faces (like we do all the time).'
Isn't that wunnerful?
